The rate limiting step in the synthesis of these compounds is the formation of malonyl-coA from acetyl coA. That reaction is catalyzed by a complex containing beta-keto acyl synthetase and the acyl carrier peptide. Prior to oxidation, these compounds are transferred to the mitochondria via a carnitine intermediate. Methyl esters of these compounds are often utilized as biodiesel, and triglycerides consist of a glycerol backbone which is esterified with three of these compounds. For 10 points, identify these substances,

For 10 points, identify these substances, which have a carboxylate group and a long aliphatic chain, whose "omega-6" and "omega-3" variants are consumed as dietary supplements.
